Results of a matched asymptotic analysis of the nucleation equation are used to obtain the "athermal" flux due to variation of the critical size. The total critical flux is also evaluated. Results, which also include estimations of crystallization rates, are used to refine the nucleation-mechanism diagram for liquid silicon proposed by J. S. Im, Gupta, and Crowder [V. V. Gupta, and M. A. Crowder, Appl. Phys. Lett. 72, 662 (1998)]. The possibility of experimental detection of athermal effects on the background of other effects of time-dependent nucleation is discussed.
